A "pilot-operated" system refers to a mechanism that uses a small control signal to manage a larger operation. This is commonly seen in devices like valves and pressure regulators, where a small pilot signal controls the flow or pressure of a larger medium. The pilot signal is typically generated by a manual or automatic control, allowing for precise adjustments. In a pilot-operated valve, for example, the pilot controls the opening and closing of the main valve. This design enhances efficiency and responsiveness, as the pilot can react quickly to changes, ensuring that the system operates smoothly. Such systems are widely used in industries like manufacturing and automotive.
